Jackson does not offer XSD generation functionality, partly since such
generators have long existed, and because
supporting XML Schema is rather complicated and metadata Jackson can
offer is bit limited with respect to special details XML handing adds
over much simpler JSON.
There are no plans to add such support.
Others may be able to point to better tools, but traditionally
`schemagen` of JAXB:

has been the way to go.
